WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 628,048, dated July 4, 1899.

Application filed June 27, 1898. Serial No. 684,641, (No model.)

To all whom it may concern.-

Be it known that we, PETER G. VAN WIE and LAZARD KAHN, citizens of the United States, and residents of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in \Vater-Heaters, of which the following is a specification.

This invention pertains to improvements in that class of devices generally termed instantaneous Water-heaters and designed for use principally in heating the incoming watersupply for bath-room purposes, the heating being effected by means of a gas-burner.

The improvementswillbe readily understood from the following description, taken ings, in which- Figure 1 is a side elevation of a waterheater embodying our improvements; Fig. 2, a vertical diametrical section of the same, and Fig. 3 a vertical central section of the'combination-cock. r

In the drawings, 1 indicates a vertical cylindrical casing; 2, a concentric enlargement of the base thereof; 3, a circular gas-burner fixed in the base of the casing; 4, a lining within the wall of the base of the casing, the rim of this lining extending upwardly and inwardly to the lower end of the cylindrical part of the casing, a sheet M of non-conducting fiber, as asbestos, being interposed between lining 4 and base-wall 2; 5, afoot-ring secured to the lower edge of base-wall 2 and supporting the casing and providing for airopenings between the base 'of'the casing and any fiat surface on which the general structure may rest; 6, a hollow projection depending from burner 3, at one edge thereof; 7, a gas-conductor leading from projection 6 diametrically across the base of the casing to near that wall of the base opposite projection 6; 8, a flanged socket clamped in an opening in the wall of the base, the inner end of this socket engaging conductor 7, the outer face of the socket being provided with airports; 9, a ported circular air-register disposed against the outerported face of socket 8 and serving in adjusting the area of the portsof the socket; 10, a horizontal gas-jet pipe with its inner end screwing into the center of the outer face of socket 8, this pipe having a flange exterior to register 9 to prevent the outward displacement of the register; 11, an adj usting-screw axially arranged injet-pipe 10 and serving as the jet-valve; 12 a pan secured in the lower portion of cylindrical casingll over the burner and over the top of lining 4 and fitting the casing-wall; 13, a central opening in the floor of pan '12, this opening being 'm'argined by an upstanding rim; 14:, the'water-di'scharge spout, projecting outwardly from the lower portion of the cylindrical casing, its inner end having water-pipe connection with the outer rim of pan 12 at a point near the floor of the pan; 15,,a crownpiece separably disposed in the top of the casing and forming a cover thereto; 16, a pipe connected with the crown-piece and serving to carry away the waste products of combustion from the apparatus; 17, the outer rim of pan 12, this rim extending well upward within the cylindrical casing and fitting the wall of the same, a sheet of non-conducting fiber being preferably'disposed between this rim and the casing-wall; 18,.a circular pan disposed within pan 12, with its fioor some distance above rim 13, the rim of pan 18 being of less diameter than that of the surrounding parts, so that products of combustion may pass upwardly around the pan; 19, a pan disposed within the cylindrical casing, with its floor some distance above the rim of pan 18, the rim of pan 19 extending outwardly close to the wall I of the cylindrical casing; 20, a central opening in pan 19, margined by an upwardly-projecting rim; 21, a pan similar to pan 18, this pan having its floor disposed some distance above the rim of pan 19, the periphery of pan 21 being less than that of the cylindrical casing, so as to leave an ann ularpassage up and around the pan; 22, a pan similar to pan 19, but disposed above pan 21, this pan 22 having a central margined opening and having its outer rim filling the cylindrical casing; 23, a pan similar to pan 18, but disposed above pan 22; 24, a circumferential series of vertical leg-pieces secured to the exterior of pans 18, 19, 21, 22, and 23 and serving to unite those pans into a single structure, the lower ends of these legpieces resting on the floor of pan 12, the outer sides of these legs engaging the inner wallsurface of that pan; 25, a pipe secured one in the floor of each of the pans except pan 12, the upper ends of these pipes projecting somewhat above the floors of their respective pans, while the lower ends of the pipes project down into the next lower pan to a point somewhat above the upper end of the pipe 25 of such next lower pan; 26, a combination-cock for controlling the flow of gas and water to the apparatus; 27, the water-inlet to the combination-cock, the same having its axis vertically disposed and being fitted for connection with a vertical pipe leading from any suitable source of water-supply under pressure, this inlet-conduit turning horizontally inward toward the casing and then turning upward; 28, a vertical pipe with its lower end screwed into the inner upper end of the water-inlet conduit, pipe 28 extending thence up along the wall of the casing and terminating in an inwardly-presenting elbow at the top of the casing; 29, a horizontal pipe screwing removably into the elbow at the top of pipe 28 and extending through the wall of the casing and radially to about the center of the casing above the rim of pan 23; 30, a clamp-collar rigidlysecured to the rim of the cylindrical casing and surrounding pipe 29 and provided with a set-screw for clamping that pipe; 31, a downwardly-presenting flaring elbow secured upon the inner end of pipe 29, the mouth of this elbow coming within a short distance of the floor of pan 23 at its center; 32, an adjusting-screw disposed in the vertical axis of elbow 31 and serving as a valve for controlling the flow through the elbow; 33, the gas-inlet to the combinationcock, the same having its axis vertically disposed inwardly beyond water-inlet 27, this inlet being prolonged inwardly toward the casing and terminating at its inner end in a downwardly-presenting elbow, the water-inlet 27 and gas-inlet 33 being integrally united by the shell of aplug-cock vertically disposed; 34, a vertical branch from jet-pipe 10, screwing into the inner elbow of gas-inlet 33; 35, the plug of the combination-cock, having a passage for water-inlet 27 and another for gas-inlet 33; 36, an opening through the base-.

wall of the casing at about the level of the gas-burner therein; 37, a pilot lighting-tube connected with gas-inlet 33 outwardly beyond plug 35, the inner endof this pilot-tube projecting toward, but not into, opening 36, and 38 a cock in pilot lighting-tube 37.

In erecting the apparatus for use the supply for water and gas is to be taken from two vertical pipes connected at inlets 27 and 33, respectively. Cock-plug 35 being turned to open position, the supply-water goes to valve 32, and this latter valve is then to be adjusted to such degree of opening as will insure against the overflowin g of the apparatus. The adjustment of valve 32 is to be effected before crown-piece 15 is put in position. I The water goes -first to pan 23, which it fills only to the limited depth measured by the upward projection of pipe 25 into that pan, the surplus quantity flowing through that pipe into pan 22,which latter pan receives a similar shallow body of water, the surplus going to pan 25, whose surplus goes to pan 19, whose surplus goes to pan 18, whose surplus goes to pan 12, whosesurplusflowsoutatspout]4. Elbow31, being near the floor of pan 23, prevents splashing over the rim of pan 23. The water in pan 23 moves to the left, that going down to pan 22 moving therein to the right and that flowing to pan 21 moving to the left, and so on, surplus water flowing in alternate directions in the pans. The regulation of valve 32 is first made relative to the pressure of supply with a view to preventing any possible overflow of the apparatus. If the gas conditions are such that the quantity of water thus regulated for is in excess of the proper heating capacity of the apparatus, then valve 32 is to have its opening still further reduced until water is delivered therefrom only at a speed within the proper heating capacity of the apparatus. The proper adjustment of valve 32 having been effected, crown-piece 15 is put in place, thus inc-losing and guarding valve 32 against tampering.

When cock-plug 35 is turned to open position to admit the supply of water, gas is at the same time admitted to the burner through jet-pipe 10, and jet-valve 11 and airregister 9 are to be so adjusted as to give the best results at the burner in connection with the given gas conditions.

In usingthe device pilot-cock 38 is to be opened before cock-plug 35 is opened, thus permitting the pilot-pipe 37 to be lighted. Then when cock-plug 35 is opened the water goes to the pans and the burner is simultaneously lighted, after which cook 38 may be closed. When cock-plug 35 is closed, the flow of water ceasesand the supply of gas becomes out off from the burner. 'The five upper pans may be removed from the casing as a single structure for inspection and cleaning. Crown-piece 15 having been removed and the setscrew in collar 30 loosened, pipe 29, with its elbow 31, maybe unscrewed from the elbow of pipe 28 and removed from the casing, after which the pan structure may be lifted out.

The products of combustion from the burner pass up through centralopeniug of pan 12, then outwardly around pan l8 and inwardly and up through opening 20 of pan 19, then out and upwardly around pan 21, thence inwardly and up through pan 22, thence outwardly and up around pan 23, and thence to escape-pipe 16.

The combination-cock and the general pipe system is supported by socket 8, which is clamped to the base of the casing. Pipe 29, with its elbow 31, being removed, the entire outer pipe structure may be turned upon the axis of jet-pipe 10, thus unscrewing thatjetpipe from socket 8, the effect of which is to separate the pipe system from the casing and to permit of the removal of air-register 9.

We claim as our invention- 1. In a water-heater, the combination, substantially as set forth, of a casing, a vertical series of pans therein arranged to receive water successively, and a circumferential series of leg-pieces extending continuously downward along the exterior of the several pans and secured thereto.
